title: [Cancer of the pancreas. IV. The characteristics of the age distribution and the location of the tumor process in the gland by sex].
abstract: Proceeding from analysis of ample postmortem material--25,589 autopsies for 25 years (1963-1987)--the authors have found that most cases of pancreas cancer were in the fourth, fifth, sixth and seventh decade of life with a peak in the sixth decade. It is important to note that the ratio by sex in the most frequently affected age groups was as follows: in the fourth and the seventh decade 3:1 in favor of males; in the fifth decade 2:1 in favor of males and in the sixth decade 1:1. The unequal proportion of cases between males and females during the fourth and the seventh decade, the relative decrease in the difference in the fifth decade and almost equal incidence in the two sexes during the sixth decade, is of definite importance for the clinical diagnosis and prognosis of the disease. Analysis of the data showed that cancer of the head of the pancreas was the most common localization both in males and in females, followed by the body, the tail and simultaneously in the head and the body. The proportion between males and females as to cancer of the head of the pancreas was approximately 2:1 in favor of males; for cancer of the body the proportion was 3:2 also in favor of males; as for cancer of the tail and of the head + body, the proportions were almost equal-2:1 in favor of males. For all other localization of cancer in the gland the proportions were statistically insignificant because of the small number of cases.
